Description

DETAILED DESCRIPTION OF THE INVENTION The present invention moves from a lower vertical guide rail provided along a ladder to an upper guide rail via a horizontal guide rail to move vertically and horizontally. Regarding a runner device for lifting and lowering in a transmission line tower, more specifically, from the upper end of the lower vertical guide rail to the starting end of the left and right guide rail, and from the terminal end of the left and right guide rail to the upper end This invention relates to a runner device for lifting and lowering a power transmission line tower, for changing the direction of the runner by 900 degrees to the lower end of a guide rail in the vertical direction and vice versa.

Unfortunately, no elevating runner device using a turn disk as described above has been proposed.

In other words, for high-rise steel towers, it is usually fine if they can be raised and lowered only vertically, but in cases such as transmission line towers, it is necessary to move horizontally at a certain height for maintenance and inspection after construction. It is necessary, and of course, where high-voltage power lines are installed, and it is especially important to prevent danger from outsiders climbing their hair, it is difficult for outsiders to climb their hair at first glance. As if holding a parent who is unable to write, the position of the ladder may be shifted halfway, for example, the upper part of the ladder installed in the front may be interrupted, and the next ladder may be placed on the side displaced by 90 degrees, so that as much as possible, outsiders can It was designed to prevent honey from accumulating. Although it is possible to prevent outsiders from entering the ladder by changing the position of the ladder as described above, it is also necessary to ensure the safety of professional workers. However, in the past, no consideration was given to this point. Therefore, in the past, when ascending and descending in the vertical direction, accidents could be prevented as much as possible by having a guide rail and a fall prevention runner that was guided by the guide rail, but as mentioned above, Accidents often occur when moving between ladders that are disposed at different positions, and it is also time-consuming to attach and detach the runners to and from the guide rails. In other words,...climb up to the upper end of the lower vertical guide rail via the vertical movement runner, connect the human body to the heavy member with the life rope carried by {0) Climb U', and move the horizontal movement runner left and right. Attach it to the guide rail in the vertical direction, then remove the life rope from the runner for vertical movement and connect it to the runner for horizontal movement (the runner for vertical movement remains attached to the guide rail in the vertical direction), and also Move the guide rail in the left and right direction via the horizontal movement runner, which is carried away from the life rope.
Reaching the bottom end of the upper vertical guide rail, {
At position E, the user had to repeat the same operations as above and then climb up the upper vertical guide rail again, which was extremely complicated and dangerous. The present invention has been made with attention to the above points, and its purpose is to move from the lower vertical guide rail to the upper vertical guide rail via the left and right guide rails, or vice versa. Another object of the present invention is to provide a runner device for lifting and lowering a power transmission line tower, which can safely change the direction of the runner. Next, an embodiment of the present invention that can achieve the above object will be described.
Figure 3 will be explained in detail.
